1 Claim.

This invention relates to wrenches and has for its object to provide a spanner wrench adjustable to various dimensions.

Another object of the invention is to provide an adjustable spanner wrench so formed as to engage either the top or the side of a device being operated upon.

A further object of the invention is to provide an adjustable spanner wrench adapted to both pull and push a screw member being operated upon.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is a side elevational view of my spanner wrench,

Figure 2 is an edge view thereof,

Figure 3 is an end view of the device,

Figure 4 is an enlarged detail perspective view of a pivot end of a jaw member and Figure 5 is a detail view of a broken away end of a jaw looking in the direction of line 5-5 of Figure 1.

In the accompanying drawings as above enu- ,merated and in the following specification, like characters of reference indicate like parts throughout and in which [0 indicates my improved spanner wrench which consists of a jaw forming shank II, and a handle end I2, to which is pivotally connected an ofiset end 13 of a shorter jaw shank I4. Also pivoted at IE, to the shank ll, adjacent to but spaced from the pivot 16, of member 13, is an adjustment plate l1, provided with an elongated slot I8, through which a set screw 19, projects, said screw being fixed to the shank [4. Threaded on the screw I 9, is a wing nut 20, which may be screwed down to fix the jaw shanks I l and M, in adjusted position. A lever handle 2!, is provided upon the end 12, of shank ll.

On the side surfaces of the jaw ends 22 and 23, are provided pins 24 and 25, adapted to enter bores usually provided in certain types of screw down devices (not herein shown), in order to screw the same tight in place, or unscrew the same as conditions require.

Provided on the facing edges 26 and 21, of the elements 22 and 23, are teeth 28 and 29, respectively, which are adapted to fit into slotted screw members (not shown), the opposite slots oi. which are provided in the sides of such members, whereby the same push and pull action is accomplished with my wrench, thus turning the member being operated upon without distortion thereof.

It is to be noted that the pins 24 and 25, project clean through said ends 22 and 23, whereby the wrench may be used from either side, depending upon the direction a screw member is to be turned.

A projection 30, on the edge 21, of shank 14, forms a notch 3|, and tooth to be used in connection with tooth 28, when there is not suificient clearance for tooth 29, to be effective.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having now described my invention that which I claim as new and desire to procure by Letters Patent is:

A wrench comprising an elongated straight shank having a handle secured on one end thereof, an offset shank pivoted to said first-mentioned shank adjacent said handle and being of less length from its pivot point to its outer end than the length of the straight shank from said pivot point to its outer end, said shanks having facing edges, gripping elements carried by the facing edges of said shanks adjacent the outer free ends of said shanks, said gripping elements extending toward each other, a slotted brace plate pivotally supported on said first-mentioned shank at a point adjacent the pivot point of said shorter offset shank, a set screw fixed to said offset shank extending through the slot in said brace plate, and a locking wing nut thereon for securing the shanks in the desired adjusted position, whereby when said wrench is disposed in operative position, a greater pull or leverage will be exerted by the ofiset shank.
